Study Notes
Movement in Living Organisms
- Movement is a universal feature of living organisms and one of the key processes of life.
Types of Movement
- Internal movement: movement of materials within a cytoplasm, such as ventilation in the lungs.
- Locomotion: movement from one location to another, allowing organisms to capture prey, obtain abiotic resources, and more.
Motile Organisms
- Motile organisms have the ability to actively move from one place to another.
- Examples: animals, such as mammals, birds, and insects.
- Functions of locomotion: avoiding danger, finding a mate, migrating, foraging for food.
- Means of locomotion: skeletal muscles, wings, flagella (whip-like structures in bacteria).
Sessile Organisms
- Sessile organisms are fixed to one place once they have established a location.
- They rely on the environment to bring food and other resources to them.
- Examples: plants, some animals, such as sea anemones.
- Movement in response to external stimuli: growth of a plant stem towards light.
Examples of Motile and Sessile Organisms
- Cheetah: fastest animal on land, can run up to 120 km per hour, adapted backbone and long tail for smooth locomotion.
- Venus flytrap: carnivorous plant, feeds on insects, traps close in response to touching hairs on its surface, digests insects with enzymes.
